Groupon, BlackBerry, Apple: Tech Premarket

NEW YORK ( TheStreet) -- Groupon ( GRPN) was a big gainer in premarket trading, rising 4.72% to $5.32, despite tumbling more than 3% during Thursday's session.

The social gamer parted company with its CEO Andrew Mason last month amid concern about the company's performance. Groupon's Executive Chairman Eric Lefkofsky and Vice Chairman Ted Leonsis are serving as interim co-CEOs, although there have been calls to make founder Lefkofsky the company's permanent chief.

The Chicago-based firm was also one of the most active premarket Nasdaq stocks on share volume of 477,686.

BlackBerry ( BBRY), which received a partner order for 1 million of its new BlackBerry 10 smartphones earlier this week, was up 0.53% at $15.14 before market open. The Canadian handset maker was also one of the most active Nasdaq stocks on share volume of 421,607.

Apple ( AAPL) shares rose 1.44% to $438.72, boosted by the tech giant's recent upgrade by BTIG. Investors also appeared to shrug off the launch of rival Samsung'sGalaxy S4 smartphone at a glitzy event in New York late on Thursday.
